eghatch03

I have a obd1 eg hatch, obd1 p75 ecu, obd1 engine harness, obd2a Ls swap out of a 98 Integra. Everything bolted in and plugged in but the injectors aren't firing. Can hear the fuel pump prime when I turn the key and I have battery positive at the black and yellow injector wire. Was wondering if it's from using an obd2a dizzy on an obd1 ecu? I made my own jumper harness for the dizzy. (Had a few engine harnesses laying around)
